Australian scientists have created a nano-structured laminated graphene paper 10 times stronger than steel.
Researchers from the University of Wollongong reported in the Journal of Applied Physics the development of nanostructural samples of graphene paper with amazing mechanical properties.
Graphene nanosheet stacks consist of monolayer hexagonal carbon lattices and are placed in perfectly arranged laminar structures which give them exceptional thermal, electrical and mechanical properties.
Using a synthesis method and heat treatment, the UTS research team has produced material that exhibits improved mechanical properties over existing graphene paper, including better bending, rigidity and hardness.
Compared to steel, the prepared graphene paper is six times lighter, five to six times lower density, two times harder with 10 times higher tensile strength and 13 times higher bending rigidity.
Not only is it lighter, stronger, harder and more flexible than steel it is also a recyclable and sustainable manufacturable product that is eco-friendly and cost effective in its use.
